Starlight Glimmer’s (Kelly Sheridan) first major appearance in My Little Pony: Friendship is Magic is as an antagonist, when she founds a village that bans individuality and strips ponies of their Cutie Marks using magic. After the Mane Six reveal that she’s a fraud, she takes revenge of them by traveling through time to wreak havoc on Equestria. She is defeated again, and Twilight Sparkle (Tara Strong) takes her under her wing as a student, beginning to teach her about the magic of friendship.
